Claims. (cl p n -1 9) This invention relates to the art of knitting machinery and more particularly .to the art of yarn moistening devices to be used on machines.

in the process of knitting to maintain the proper 5 amount of moisture in the yarn or yarns as they travel from the source of supply to the needles.

Other objects and advantages of the invention will appear more fully herein.

The invention consists substantially in the I combination, construction and relative arrangement of parts, all as will appear more fully hereinafter, asshown in the accompanying drawings 5 and as finally pointed out in the appended claims.

In the accompanying drawings, wherein has been illustrated the preferred embodiment of the present invention:

on the line 8-8 of Figure 3;

' Figure 9 is a longitudinal sectional view taken on the line 9-9 of Figure 3;

Figure 10 is a perspective view of the mois tening deviceshowing the several parts in separated relation; and

Figure 11 is a perspective view showing the 5 device in assembled condition.

'as clearly appears in Figure 5. Inside the box the yarns therefrom as will be explained, that Referring now to the drawings and more particularly to Figure ,1, the invention is illustrated in position on avfull-fashioned knitting machine, the upper rear frame of which is designated by the reference numeral II on which is supported 5 the usual yarn conditioning chamber [2 in which one or more cones of yarn l3 are supported. The chamber I2 extends longitudinally of the machine to accommodate the necessary number of yarn CODES. 10

The yarns fiioiifthe conesv l3 pass upwardly from the chamber l2, passing through the guides I4, and as shown at l5, pass to the open faced moistening device or wetting trough l6, also extending longitudinally of the machine and supl5 ported, in any suitable manner, by the frame ll of the full-fashioned knitting machine. The moistening device IS-is here shown as comprising two sections but obviously the number of sections in each device may vary and the number of devices used on each machine may likewise vary dependent upon the number of needle sections in the machine.

The device l6 includes an open face box l1 containing any suitable liquid yarn wetting agent,

l'|,,and extending lengthwise on the longer sides thereof,- are the ledges I8 which are spaced 2. short distance from the top of the box and extend inwardly. The ledges l8 support the yarn 3o guiding means to be described so that the yarns may extend down into the liquid.

the ledges l8 in the box II. It will be apparent that when the yarn guiding means are removed, as in Figure 5, without the necessity of removing then the box I! is easily accessible for cleaning and inasmuch as it is often necessary to clean the g box l1, this feature of my invention is very important. e r V The device l6 also includes the yarn guiding 45 means having the rectangular open frame IS with longitudinally extending ledges 20 extending along the longer sides of the frame and inwardly site end walls of the frame l9, as well as to the u "Ion means of the overhangng lips 30 which engage rib 2d are the brackets 22 having the supporting ledges 23, as clearly appears in Figure 2, one of these brackets 22 being shown in perspective in Figure 7. The brackets 22 are positioned so that the ledges 23 are spaced a short distance away from the adjacent longer side wall of the frame 89 as clearly appears in said Figure 7, these ledges 23 being further disposed a short distance above the ledge 20.

The reference character 24 designates a longitudinal shelf which is supported by the ledges 23 of the brackets 22, the shelf being retained in position on the frame i9 by means of the depending lips 26 and the depending lugs 2'3 (Figure 6) which fit over the ledges 2 3, as may be clearly seen in Figure 3. The shelf 24 is adapted to support the usual felt strip for removing excess moisture from the yarns as they travel in contact with and past the felt, it being noted that the shelf 24 is provided along its inner edge with a longitudinally extending upright flange 25 in which are provided a plurality of eyelet guides 24.

While in the construction illustrated the shelf 24 for supporting the felt strip is shown in the form of a detachable element which is removably supported in position upon the ledges 23 of the brackets 22, it will be understood that this shelf may be formed as an integral part of the removable frame I 9, in which event, the shelf, designated 24, would constitute the base of a relatively shallow trough extending lengthwise of the frame l9 immediately adjacent one side wall thereof, the opposite side walls of this trough being provided with a plurality of longitudinally spaced eyelet guides for guiding the yarn or yarns out of the main liquid trough and across the felt supported upon the shelf 24. In either event, whether the felt shelf be formed as an integral part of the frame l9 or as a readily removable element, the outer longitudinally extending edge of the shelf is spaced from the proximate side wall of the frame i9 as well as from the supporting ledge 20 of the latter to provide a free opening 30 (see Figures 3 and through which excess liquid accumulated by the felt strip as the yarns pass thereover may flow back into the box I! containing the main supply of said liquid.

The glass float tubes are designated by the character 28 and these serve as guides for the yarns to cause them to travel through the liquid in the box H. The means supporting the glass tubes 28 are the hangers 29, each of which is slotted to removably receive the ends of the float rods and to carry them inside the box H. The

extreme end wall hangers 29 are secured in place the opposed end walls of the frame l9 by over the upper ends of said end walls, while the intermediate hangers 29 are secured together and are suspended as a unit over the intermediate transverse rib 2| of the frame l9. 'It will be obvious that the lips 30 may be permanently secured to the frame l9 rather than removably secured as shown. It is preferred; however, to removably secure the hangers 29 in position because in such event the latter may be removed from the frame [9 in order to render the glass tubes 28 accessible for cleanng or replacement without efiecting disorganization of the frame I9 with respect to the main box l1.

Suitable eyelets, preferably porcelain, are provided as shown to guide the yarns and specifically these eyelets are in both of the longer side walls of the frame I9, and in the upright portionof the shelf member 24. A su'table number of these eyelets are provided and the yarns l5 pass .through those on the right side of the frame i9 (Figure 3); then down and under the tubes 28, then up and through the eyelets in shelf member 24, then through the eyelets on the other side of the frame, and then on to the yarn guides feeding the yarn to the needles.

It will be noted that all of the yarn guiding means are secured to the frame l9, including the glass tubes 28 for training the yarns through the liquid wetting agent and the felt strip for removing excess liquid from the yarns. Thus, as the frame 19 is removed from the box l'l, all of the yarns are carried along therewith out of the box l1 and still threaded through the eyelets, glass tubes, and felt strip means. After the box H is cleaned, the frame H) with the yarns still threaded, may be lowered back in position in the box i1. Thus, it will be seen that with a minimum of effort, the box I1 which requires frequent cleaning, is readily and easily accessible for that purpose, and the trough may be dismantled as shown in Figure without the necessity of cutting or in any way disturbing the threads which pass from their supply source to the knitting machine.

What is claimed as new and useful is:

1. In a yarn moistening device for a full-fashioned knitting machine, in combination, a rectangular container for a liquid yarn wett ng agent, a readily removable rectangular frame member supported by said container, and means carried by said frame member for supporting a plurality of longitudinally extending floats within said container for guid ng yarns through said liquid.

2. In a yarn moistening device for a full-fashioned knitting machine, in combination, a rec tangular container for a liquid yarn wetting agent, a readily removable rectangular frame member supported by said container, means on said frame member for supporting a plurality of longitudinally extending tubular floats within said container for guiding yarns through said liquid, and a longitudinally extending shelf member on sa d frame member for supporting a felt strip to remove excess moisture from said yarns.

3. In a yarn moistening device for a full-fashioned knitting machine, a rectangular container having inwardly projecting ledges extend ng longitudinally along opposite side walls of said container, a readily removable rectangular frame member extending within and supported by said container ledges, brackets on said frame member for supporting a plurality of longtudinally extending floats within said container for guiding yarns through said liquid, and additional brackets on said frame member for detachably supporting a longitudinally extend ng shelf member in position adjacent said floats for supporting afelt strip to remove excess moisture from said yarns.

4. In a yarn moistening device for a'full-fashioned knitting machine, in combination, a main container for a liquid yarn wetting agent, a readily removable open frame member supported within the top of said container, means carried by 2,182,578 guiding elements may be raised upwardly and out carried by said frame member for suspending interiorly of the container a plurality of longi-' tudinallyextending laterally spaced yarn guiding element, said frame member and the element supported thereby being separable from the con- 5 tainer at will whereby to permit the removal of said frame member and itsassociated parts including yarns threaded therethrough from the container in order to render the latter clear of said yarns and yarn guiding means for cleaning 1 and other such purposes.
